TheV present -invention relates to improvements in therapeutic gasgenerators, and has for an ob'ect to provide an improved medicinal gasi'ng device for administering gaseous `medlcaments through the mouth andnose.

Another object of the Vinvention is to provide a compact and simple formof device having a high atomizing action and adapted to quickly gasifythe liquid medicine.

A further object of the invention is to provide anim roved gasifyingunit which will have the e ect to secure purity of gas and a propermixture and proportion thereof.

With the foregoing and other objects in View, the invention will be morefully described hereinafter, and will be more particularly pointed outin the claims appended hereto.

In the drawings, whereii like symbols refer to like or correspondingparts throughout the several views, I

Figure 1 is a vertical sectional view taken through an improvedtherapeutic gas generator constructed in accordance with the presentinvention and shown as applied for use. Fi re 2 is a horizontal sectiontaken on the line 2- 2 in Figure 1, and

Figure ,3 is a perspective view of the im-l proved gasiying unit.

Referring more particularly to the draw ings, 5 designates the lowerportion of a bronze or other container in which the liquid body of themedicine is contained and indicated at 6. In the upper globular portion7 of the container which encloses the gas space, is arranged thegasifying unit and supported therein in any appropriate manner. Thisunit includes the cylindrical wall 8, from the lower edge of whichextends the inverted conical bottom 9.

The liquid suction tube extends up through the center of the conicalbottom 9 c flange 31 to directthe liquid medicine down into the lowerportion 5 of the container. vA 96 and its lower end is immersedin theliquid body 6. The upper end of the suction tube 10 extendsfintb asocket in a nozzle block 11 mounted within the container wall 8 andhaving therein the conical nozzles -12 and 16, the axes of which aredisposed at substantially right angles whereby the jets oi' streams from29 the nozzles will intercept one anotherat a point just beyond suchnozzles.-

The vertical nozzle 12 is an extension of the socket in which thesuction pipe 10 is fitted; while the horizontal nozzle 16 com- 55municates with a space 17 into which the compressed air pige 18 is screwthreaded or otherwise remova ly connected. f

This compressed air ipe extends up `lthrough the container wal 8 andconnects so with passages 19 in the top cover 20 of the device. Thepassages 19 connect with a pipe V21 in communication with a source yofcome pressed air sup` ly. The cover is provided with a remova le plug 22through which the 66; medicine 6 may be introduced into the device. Thiscover 20 is also provided wit a connection for the flexible tube 23 towhich the face cover or hood 24 is attached. This hood 24, in Figure 1,iszillustrated as extending over 'l0` the face of the patient. Y

A baille plate 2,5 is disposed within the container 8 and is diagonallydisposed extending from the junction of the wall- 8 with the bottom 9.at a point remote from the nozzle block 75 l 11 and extending updiagonally toward and above the nozzle block and intercepting the streamof compressed air issuing from the` nozzle 16. The side wall 8 isprovided with one or more perforations 26 at the base thereof just abovethe point of connection with the baffle 25. The hopper bottom 9 is alsoprovided with.one or more drain openings 27.

A screen 28 is stretched across the gasiying 85 chamber within thecontainer 8 just above the nozzle block 11 and upper end of the bameplate and a second vertical screen section 29 surrounds the upperropenportion of the chamber and forms substantially a continua -90- tionof the side wall 8. e This screen section 29 may be carried by a` cover30,formed with a downturnedmarginal boss upon the cover 30 provides forreceivingl the compressed air pipe therethrough. The

container wall 8 is formed with a'shoulder 33 at its upper end toreceive the screen section l In the use of the apparatus, com ressed airis turned into the pipe 21, descen through the pipe 18 and enters thenozzle 16, from which it issues in a minute stron stream.

l This stream crosses the mouth of t e nozzle 12 causing a suction ofthe liquid medicine 6 up through the suction tube 10. This liquidmedicine is ent'rained with the jet of compressed air and the mixtureimpinges against l0 the bale plate 2'5, being broken up and gasiiiedthereby, and deflected downwardly toward the hopper or conical bottom 9,.which will catch any precipitated liquid, allowing the excethereof toflow out through the 15 drain openings 27. The gas will riseupwardlythrough the screen 28 which will strain out foreign matter.

The horizontal screen 28 will have a like eiect and the depending fiange31 will cause 90 the gas after passing through the screen section 29'tobe deflected downwardly, thus providing a baie surface on which anyparticles of moisture may lodge and drip down into the container below.The puregas goes 25 out through the tube 23 to the hood 24 and isinhaled by the patient.

The device may rest upon a base 34 if desired having an electric orother heating unit 35 therein, which will raise the temperature 3 of theliquid medicine body 6, thereby increasing its tendency to gasify. Thefine mesh screens will act to atomize and break up the mixture.

The oily, aqueous or alcoholic solutions I a5 are atomized to such anextent that they can enter the red corpuscles of the lungs and becarried to all parts of the body by the blood. This requires the finestand driest form of gaseous drugs; atomized and nebulized 0 vapors beingunable to enter the red corpuscles.

It is obvious that various changes and modifications may be made in thedetails of construction and design of the above specifically describedembodiment of this invention Without departing from the spirit thereof,such changes and modifications being restricted only by the scope of thefollowing claim.I '5 what is claimed is:-

In a therapeutic gas generator, a gasifying unit for inhalingdevicescomprising a cylindrical container Wall having an invertedconical bottom, a suction tube entering through the bottom, a nozzleconnecting with the tube, a compressed air nozzle angularly disposed tothe medicine nozzle, a diagonal baiiie plate extending in front of andabove said nozzles, a fine screen stretched across said container abovethe nozzles and bale plate, a cover having a marginal downwardlydirected flange, and a screen stretched between the cover and wall ofthe container.
